Every F and G rated home around a postcode — the properties that cannot legally be let without a registered exemption, and whose owners face a five-figure upgrade bill or an exit. Cross-referenced against 4.5 million corporate ownership records so you can see which ones belong to landlords, then straight into the X-Ray, the map and the owner's whole portfolio.
⚠ MEES: letting an F or G rated home is unlawful without a registered exemption, and the rental minimum is proposed to rise to C by 2030. That's a real bill or a real sale. EPCs last 10 years — confirm the current rating before you act, and check the register for an existing exemption.
